I have a mid 2010 iMac that has for years had trouble with "pausing" ever once in a while. The original HDD died a few years ago, and I assumed that was the problem and replaced it with an SSD. Lots of stuff was faster, but it still would hang from time to time. I also upgraded it to 16GB of RAM, and it still would hang. For a while I thought it was just OS X, but I have a year older Mac Mini with a 2GHz C2D, 4GB of RAM and a HDD, and it never hangs like this. Boot up and app launching take longer, but this is something different.
I recently backed everything up and did a full reinstall, and swapped in different RAM chips, still the same issue. I also ran the Hardware Diagnostics (including the long form) from the discs that shipped with it. I had to put a jumper in the HDD temperature probe to get it to pass that step.
It can be almost anything, doesn't need to be taxing the computer, but I think it happens more often when doing something heavier. Everything is running smoothly, then it just stops responding or showing anything on the screen for ~3 seconds. Even iTunes can't play a song without stopping once in a while (but I didn't seem to have much trouble playing in Vox).
I'm out of ideas to test. I was really hoping the hardware diagnostic would tell me there was a bad RAM chip, but it didn't.
Any ideas on other things to test or try?
